A dance-pop tune released in September 2025 by Wooyoung, who also shines as the main dancer of the popular group 2PM.

It marks his first Korean solo comeback in about seven years and serves as the title track of his mini-album “I’m into.” Wooyoung himself wrote and composed the song.

It carries a self-empowering message that urges his overthinking self to take that first step—“There’s no time, move now.” Its brisk beat and energetic sound blow away hesitation.

The contrast between Wooyoung and featured artist Damini adds even more appeal to the track.
